Application filed May S, 1883.

proper, and c a its loops. rlhe latter are formed `To all whom t may concern.-

Bet known that I, AMAsA W. SrnvnNs, a citizen of the United States, residing at East Brookfield, in the State of Massachusetts, have invented a new and usefu-l Improvement in Barbed Fence-Wire, of which the following is a specification.`

to a single main Wire by bends, in contradistinction to perforations and the like. Heretofore barbed wire of this class has been open to either or both of two serious practical objections-wiz., complexity of bends, `precluding cheapneSS, by rendering its manufacture by machinery difficult or impossible, and insecurity as against the effect of the longitudinal strains to which fence-wire is subjected in' stretching it between the fence-posts.

The present invention consists in barbed fence-wire comprising several novel features of construction or arrangement of bends, here inafter set forth and claimed, whereby, respectively, singlecoil bends in the barb-wires, heretofore proposed for attaching barb-wires to a looped main wire, are securely guarded against being opened by strain on the latter,

the yielding of the loops in the main wire is limited, and they are kept from opening under strain, and each barb-wire is attached by a secure knot formed` by uniform coil-bends in the respective wires, and adapted to tighten under strain, while manufacture is further.` facilitated by forming all the main-'wire loopsin one and the same direction, so as to avoid reverse movements, and they may at the 'same time be conveniently located on different sides of the wire, so that the barbs shall project alternately at differentangles.

A sheet of drawings accompanies this speciiication as part thereof. Figure l of these drawings is a perspective view of a piece of barbed fence-wire embodying all the several features aforesaid. Fig. 2 represents a crosssection thereof, showing a side view of one of its barbwires5 and Fig. 3 is a side elevation of a portion, showing an end view of a barb-wire.

Like letters of reference indicate corresponding parts in the several figures.

A represents the :main wire or feneewire by single-coil bends, which are readily formed by machinery. This is further facilitated by forming all the bends in one and the same direction, as shown, and by simply turning the wire one-fourth of a rotation after each loop is bent, either continuously (step by step) or back and forth, the loops a are located on different sides of the wire alternately, as shown.

B B B represent barbwires, and b b their at taching-loops, which are identical in form with the loops a of the main wire, and may consequently be formed by similar movements, and with the utmost economy of movement and metal. The barb-wircs are intended to be cut successively from a reel of wire of the same gage as the main wire, or thereabout. In so forming each barb-wire B, and attaching the same according to this invention, one end (the free end of the reel-wire) is passed through a loop, a., of the main wire A, then bent back around the double or crossing point of the loop a, and again passed through the same loop, thus completing a loop, b, followed by severing the barb-wire from the reel. Each barb end may be sharp-pointed in t-he act of severing the wire, or subsequently by independent means', as may be preferred. The double knots formed by the coil-bends ab are best seen in Fi l. Eacl1 barb-wire is thus securely knotted to the main wire, so that strain on thelatter tends to tighten the attachingloops, and stretching under strain is limited. The location of t-he double or crossing point x of each maiirwire loop a within a barb-wire loop, b, whereby the main-wire loops more particularly are guarded against destruction by strain, is best-seen in Fig. 2. The location of the double or crossing point rv of each barb-'wire coil b within a main-wire coil, c, whereby the 1at`` ter is caused to lock the former securely against opening when the main wire is stretched or under strain, is best seen in Fig. 3. The latter is the principal distinguishing feature of my invention, and is considered of vital iniportance.

That l claim as new, and desire to patent under this specification, is*

l. Afenee-wire having loops at any desired distance apart, and provided with transverse barb-wires interlocked with said loops by singie-coil bends, the double or crossing point of lOO each barb-wire being located Within the coacting loop of the fence-Wire, so as to be embraced by the latter and locked by this embrace when the fence-Wire is stretched, substantially as herein set forth.

2. A fence-Wire having loops at any desired distance apart, formed by single-coil bends, and provided with transverse barb-wires interlocked with said loops by similar coil-bends, the double or crossing point of each barb-wire being located within the coacting loop of the fence-Wire, and the double or crossing point of the` latter within the loop of the barb-wire, as herein described, for securing the loops of thefence-wire against opening or spreading under strain, in the manner set forth.

3. A fence-wire having loops at any desired distance apart, formed by single-coil bends in one and the same direction, and provided with transverse barb-Wires interlocked with said 2o loops by similar coil-bends, the double or crossing point of cach coil-bend being located Within and embraced by the coacting loop, as herein specified, thereby attaching the barbs by knots composed of uniform loops in the re- 2 5 spective wires, as set forth.
